Solution

1. Preparation

Gather tools and parts needed: OBD-II scanner, multimeter, socket set, replacement radio fuse (if applicable), and possibly a new radio unit.
Ensure the vehicle is parked in a well-lit area and the engine is turned off.

2. Inspect the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and locate the fuse for the radio (consult the owner's manual for the exact location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for a break in the filament. If it appears blown, replace it with a fuse of the same amperage (typically 10A or 15A for radios).

3. Check the Wiring

Disconnect the negative terminal of the battery to prevent electrical shorts.
Remove the radio from the dashboard by unscrewing the mounting screws.
Inspect the wiring harness connected to the back of the radio for any visible damage or loose connections.
Reconnect the wiring harness securely, ensuring all connections are tight.

4. Test Power Supply

Reconnect the battery terminal and turn the ignition on.
Use a multimeter to check for voltage at the radio's power connector; you should see approximately 12 volts.
If no voltage is present, trace the wiring back to the fuse box and ignition switch, checking for continuity or breaks.

5. Reinstallation

If the radio is functioning correctly, carefully reinstall it in the dashboard.
Secure all screws and ensure that the wiring harness is properly tucked away.
Reconnect the negative battery terminal.
